Loudspeaker

Abstract

A loudspeaker is proposed, having an enclosure where the following components are installed: a magnetic circuit, a permanent magnet, a coil, a system positioning the coil in the gap between the enclosure and a permanent magnet, a resonating membrane diffuser, attached by an attachment mechanism to the coil, and lead wires with terminals. The coil is star-shaped. The technical result is to increase the loudspeaker's power and efficiency, to reduce its weight and size, and to improve the sound quality.

The invention claimed is: 
     
       1. A loudspeaker comprising:
 an enclosure having installed therein:
 a magnetic circuit, 
 a permanent magnet with a gap between the enclosure and the permanent magnet, 
 a coil having a plurality of turns, wherein each turn of the coil is formed into a star shape configuration having a plurality of alternating beams and cavities, and 
 
 a system configured for positioning the coil in the gap between the enclosure and the permanent magnet; 
 a membrane attached by an attachment mechanism to the coil; and 
 lead wires attached to terminals and to the coil. 
 
     
     
       2. A loudspeaker according to  claim 1 , wherein each beam of the plurality of beams of the turns of the coil has a respective beam end, and each beam end has a respective shape of at least one of an angle, arc, or rectangle; or a combination thereof.
